The Teknofanghi Teknobag Draimad® Bag Filter offers a robust, efficient, and environmentally friendly solution for sludge dewatering in water and wastewater treatment plants. Its advanced design and high-efficiency filtration capabilities make it an ideal choice for facilities seeking to optimize their sludge management processes. The system’s cost-effectiveness, versatility, and ease of operation further enhance its value, making it a reliable and sustainable option for various dewatering applications.
The Teknobag Draimad® Bag Filter system is a highly efficient and versatile solution for sludge dewatering, designed to handle various types of sludge from water and wastewater treatment processes. The system operates based on a combination of gravity and pressure filtration within specially designed filter bags.
Principle of Operation
Key Steps
Sludge Loading
Sludge is pumped into the filter bags, which are suspended within a frame. The bags are made from a specially woven fabric that allows water to pass through while retaining the solid particles.
Filtration and Dewatering
- As the sludge enters the bags, water starts to filter through the fabric under gravity, while the solid particles are retained within the bag. This initial stage significantly reduces the water content.
- Over time, the increasing solids concentration within the bag creates a natural pressure differential that enhances further dewatering.
Drying
The dewatered sludge remains in the bags, where it continues to dry through evaporation and further drainage. The design of the bags ensures maximum air flow, facilitating the drying process.
Pressurization Option
The optional pressurization facility enables the dewatering time to be decreased and increases the quantity of sludge which can be treated. This is due to the higher dry solids concentration achieved inside the bags, reducing the working time and bag consumption.
Draining Bags
The heart of the system is the draining bag, made from a special “TNT” water repellent material, very resistant and inert to: chemicals, acids, bacteria and insects.
Flexibility
The TEKNOBAG-DRAIMAD® system are offered in about 30 different models, ranging from the small manual units, to the fully automatic and pressurised units. If it is found necessary to increase the sludge capacity of a plant where a bag-module is already installed, an additional bag-module can be added and connected using the existing flange and saving additional costs.
